NCLEX Questions Urinary System Questions
Question 1 of 5
Renal ammonium ion excretion is increased by aldosterone, elevated blood pCOâ‚‚ and acidemia
Correct Answer: A
Rationale: Aldosterone, high pCOâ‚‚, and acidemia boost ammonium (NHâ‚„âº) excretion (A) in the collecting duct and proximal tubule to excrete H⺠during acidosis. Aldosterone enhances H⺠secretion, pCOâ‚‚ and acidemia stimulate ammoniagenesis, making A (true) correct over B or added options.
Question 2 of 5
The ___ artery sits on the boundary between the cortex and the medulla of the kidney.
Correct Answer: C
Rationale: The arcuate artery (C) lies at the cortex-medulla junction, branching from interlobar arteries. Lobar (A) and interlobar (B) are deeper, and segmental (D) is proximal, making C the boundary vessel.
Question 3 of 5
Which information will the nurse include when teaching the patient with a urinary tract infection (UTI) about the use of phenazopyridine (Pyridium)?
Correct Answer: C
Rationale: Pyridium turns urine reddish-orange (C), a key teaching point for patient awareness. It's used short-term (not 7 days, A), doesn't require sunscreen (B), and isn't preventive pre-intercourse (D), making C the essential information.
Question 4 of 5
A patient who has had a transurethral resection with fulguration for bladder cancer 3 days previously calls the nurse at the urology clinic. Which information given by the patient is most important to report to the health care provider?
Correct Answer: B
Rationale: Urine clots (B) post-procedure suggest bleeding, requiring urgent provider attention. Opioids (A), anxiety (C), and nocturia (D) are expected, but clots indicate a complication, making B most critical.
Question 5 of 5
A 78-yr-old patient has been admitted with benign prostatic hyperplasia. What is most appropriate to include in the nursing plan of care?
Correct Answer: B
Rationale: The patient's age and diagnosis indicate a likelihood of nocturia, so leaving the light on in the bathroom is appropriate. Fluids should be encouraged because dehydration is more common in older patients. The information in the question does not indicate that measurement of the patient's output is necessary or that the patient has overflow incontinence.
